A horizontal pipe fixing device for mechanical processing

Abstract

The invention discloses a horizontal pipe fixing device for mechanical processing, which comprises a base, a stepping motor is fixedly connected to the base, two first mounting seats are symmetrically fixedly connected to the base, and the two first The mounting bases are all fixedly connected to the outer wall of the stepping motor, and a threaded shaft is rotatably connected to the first mounting base. With the help of the forward and reverse rotation of the stepping motor, the invention drives the threaded shaft to rotate through the movable gear, and then drives the water tank to move up and down in the vertical direction, and controls the water pressure in the conduit by controlling the height of the water tank, thereby realizing the clamping of the pipe by the fixed die. The clamping force is controlled, so that the clamping force of the fixed die on the pipe is controllable, and can be adjusted according to the material and load-bearing performance of the pipe to be processed, so it can effectively prevent the pipe from being damaged due to excessive clamping force. It is extruded and deformed, and can effectively avoid the problem of weak clamping caused by too small clamping force.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a horizontal pipe fixing device for mechanical processing. Background technique [0002] Pipe is a material that is often used in the process of mechanical processing and manufacturing. In order to meet the needs of use, processes such as cutting and punching are often performed on its surface. In order to ensure the processing accuracy and quality of the pipe, at the same time to ensure In order to ensure the safety during production, it is necessary to clamp and fix the pipe to be processed before processing. [0003] At present, the clamping and fixing of pipes is usually realized by using V-shaped clamps, but the contact area between the V-shaped clamps and the pipes is very small, and a good clamping and fixing of the pipes requires a relatively large clamping force, so it is easy The sag of the pipe is caused by the excessive pressure of the contact part. If ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the clamping and fixing of pipes is usually realized by using V-shaped clamps at present, but the contact area between the V-shaped clamps and pipes is very small, and the pipes Good clamping and fixing requires relatively large clamping force, so it is easy to cause the pipe to sag due to excessive pressure on the contact part. If the clamping force on the pipe is reduced, the maximum static friction force of the contact part between the clamp and the pipe will be too The small size makes the pipe easy to rotate during processing, which seriously affects the quality of pipe processing
